Wt，%

 

C	Si	Mn	P	S	Mo	Ti	Nb	B
≤0.09	0.20 ～0.50	1.30 ～ 1.60	≤0.020	≤0.010	0.20 ～ 0.50	0.010 ～ 0.030	≤0.08	≤0.0030

Note: (1) the supplier can  added other trace elements.

（2）Ceq≤0.42%,Ceq(%)=C+Mn/6+(Mo+Cr+V)/5+(Ni+Cu)/15

(3)Pcm≤0.20%,Pcm=C+Si/30+Mn/20+Cu/20+Cr/20+Ni/60+Mo/15+V/10+5B

Other did not involve parts still should comply with the WYJ028-2005 "WHT590 steel supply the technical agreement" regulation.
